Safety and efficacy of cervical 10 kHz spinal cord stimulation in chronic refractory primary headaches: a retrospective case series

Background Paresthesia-free cervical 10 kHz spinal cord stimulation (HF10 SCS) may constitute a novel treatment modality for headache disorders, when pharmacological approaches fail. We report the results of a retrospective analysis assessing the long-term safety, tolerability and efficacy of HF10 SCS in a group of patients with chronic refractory primary headache disorders.
